Data from: Interactions between sexual signaling, thermoregulation and body size drive ecology and evolution of wing colors in Odonata

This dataset consists of images of the fore and hind wings (and associated metadata) of 4091 individual odonate specimens, and thus over 8000 wings, imaged on a commercially-available Epson desktop flatbed scanner and color-calibrated using a color-checker, comprising the Targeted Odonata Wing Digitization dataset (TOWD; https://digitizingdragonflies.org/) The odonates imaged are all from the Nearctic, and represent 343 species. In this dataset, 47% of images come from the Alabama Museum of Natural History (ALMNH), 19% from the PhD thesis collection of William Kuhn (now housed at the American Museum of Natural History, AMNH), 19% from the collection of the late Michael L. May, and 13% from Jessica Ware’s Rutgers-University Newark collection (now housed at the AMNH). Files are individual PNGs where transparency is the background. Metadata includes species, sex, and county.
